BIAS T (OPTION 10) VERIFICATION
a.
Equipment Required:
·
AC-DC Adapter Power Supply 40-115
·
Open/Short, Anritsu 22NF50
·
100 Ohm, 1 Watt load (100 Ohm, 1 Watt
resistor soldered from the center pin to
ground of an N-type connector.)
b.
Procedure:
1.
Connect the AC-DC Adapter Power Sup-
ply to the battery charging port on the
Site Master (Option 10 only works with
the AC-DC Adapter).
2.
Apply AC power to the power supply.
3.
Press and hold the
ESCAPE/CLEAR
key,
then press the
ON/OFF
key to turn on
the Site Master. (This sets the instru-
ment to the factory preset state.)
4.
Press the OPT soft key.
5.
Press the B3 soft key to activate the Bias
Tee option.
6.
Verify that the display shows
BIAS ON,
15.0 V, 0 mA
.
7.
Connect the 22NF50 short to the Trans-
mission test port.
8.
Verify that the display shows
BIAS ON,
Fault
, and the test port voltage relay
clicks on and off.
9.
Remove the short and install the 100
Ohm load.
CAUTION
The 100 Ohm resistor will get hot.
Verify the readings and remove
the 100 Ohm load immediately.
10.
Verify that the display shows
BIAS ON
,
with a reading of 14.8 to 15.3 Volts, and
120 to 160 milliamps.
